DIY Laser Spirograph

Step 7 Closing Thoughts

You don't need a switch as you can just twist and untwist two wires if you must.

The problems with wiring in parallel isn't too apparent here, probably because the potentiometer has pretty low resistance and i think it isn't worth it to wire in a series.

To keep the laser on, try using a zip tie over the button. The way the ties are made is that you can just twist them too and they will turn off the laser.

If you dont want to make the laser stand you could try to put the laser on a book or something to try and get the angles right. The instructable for using flour as a camera holder will work good, using a laser instead of a camera of course.

A great place for high powered lasers is Wicked Lasers. Only buy lasers there if you buy goggles too, any laser over 5mW can be very devastating to eyesight.

Thanks for putting this wonderful instructable - I will make one as soon as I can

One possible modification could be that one could fix toothpaste caps (or something similar) to shafts of the motors - and stick mirror to cap using plastic clay or something like that.

Now you can experiment with different reflecting surfaces and materials - such as CDs or DVDs -

you could try small computer fans and bluetack

this is not a bad idea i wonder if we could add more to this like an arduino instead of brush type motors why not some bi- polar motors and servos to control the X-Y

[supercrazytutorials]

can i coonect it with the output audio jack of my pc???????

[trooperrick]

No, but there are a whole bunch of other instructables that will show you other designs.
